Low-density elongated stone porcelain ceramic plate and preparation method thereof
The invention discloses a low-density elongated stone porcelain ceramic plate and a preparation method thereof. The green body powder of the low-density elongated stone porcelain ceramic plate is prepared from, by mass, 5.0 to 7.0 percent of ignition loss, 60.0 to 64.0 percent of SiO2, 21.0 to 24.0 percent of Al2O3, 0.35 to 0.55 percent of Fe2O3, 0.1 to 0.3 percent of TiO2, 2.5 to 4.5 percent of CaO, 0.3 to 0.9 percent of MgO, 2.0 to 4.0 percent of K2O and 1.0 to 2.5 percent of Na2O. According to the ceramic plate, a CaO-MgO-K2O-Na2O multi-element composite flux system is adopted, multi-element crystalline phases such as elongated stone, mullite and quartz are formed through high-temperature firing, the stress among the multi-element crystalline phases is released, the firing shrinkage rate of the green body can be obviously reduced, and the fired ceramic plate has the characteristic of high strength.
本发明公开一种低密度拉长石质瓷质陶瓷板及其制备方法。所述低密度拉长石质瓷质陶瓷板的坯体粉料的化学组成包括：以质量百分比计，烧失：5.0～7.0%、SiO2：60.0～64.0%、Al2O3：21.0～24.0%、Fe2O3：0.35～0.55%、TiO2：0.1～0.3%、CaO：2.5～4.5%、MgO：0.3～0.9%、K2O：2.0～4.0%、Na2O：1.0～2.5%。所述陶瓷板采用CaO‑MgO‑K2O‑Na2O多元复合熔剂的体系，经高温烧成形成拉长石、莫来石、石英等多元晶相，使多元晶相之间的应力得到释放，还可明显降低坯体烧成收缩率，促使烧成后的陶瓷板具有高强度特性。
